Patented Mar. 24, 1931 UNITED STATES PATENT oF-FICE I JAMES W.MCCLINTOCK, OF L'OSVANGELES, CALIFORNIA, ASSIGNOR :TO E-Z REACH PAPERCUTTER CORPORATION, LTD., OF LOS ANGELES, GALIFORNIA, A CORPORA` TION OFCALIFORNIA v ROLL-PAPER CUTTER Application filed Ma1ch-22, 1928.SerialfNo. 263,63?.

and the front portion of said plate is cur-ved I My invention relates toa roll paper cutter downward to a slight degree and the edge ll and hasfor its principal object, the provision of a relatively simple,inexpensive and convenient device that is capable Vof being readilyvcombined with a roll of wrapping paper' for supporting the web of paperas it is unw'ound from the roll, and said device being provided with astraight edge along which the web of paper may be torn.

A further object of my invention is to provide a roll paper cutter witha. roller over which the web of paper` passes as it is un-` wound fromthe roll, said roller having combined therewith friction devices t-hatare instrumental in preventing the paper from unwinding too freely, andsaid friction devices being formed so as to deflect the end of the webof paper downwardly away from the tearing edge where said free end maybe readily grasped to permit a portion of the web to be unwound from theroll, and torn off by engagement with the edge of the cutter. A furtherobject of my invention is to provide a roll paper cutter that may beconveniently combined with a holder and a roll of paper, or said cuttermay be located on a suitable support above or in front of a roll ofpaper, and which latter may be mounted at any convenient point, forinstance, beneath a counter or on the top, side or end of a counter,showcase or the like.

With the foregoing and other objects in View, my invention consists incertain novel features of construction and arrangementof parts that willhereinafter be more fully described and claimed and illustrated in theaccompanying drawing, in whichig. l is a perspective view of a rollpaper cutter constructed in accordance with my invention.

Fig. 2 is an enlarged cross section taken on the line 2 2 of Fig. l.

Fig. 3 is an end elevational view of the cutter.

Fig. 4 is a top plan view of the end portion of the cutter.

Referring ing drawings which illustrate a practical embodiment of myinvention, designates a plate preferably constructed of sheet metalVtio-ns of these slots aretrunn1ons217 that by numerals to theaccompany-` of said downwardly curved portion consti-v tutes a tearingedge-against which the web of paper is engaged and torn.

rojecting vrearwardly. from the endA portions of plate 10,1are shortintegral arms l2 that occupythesame horizontal planewith `the body ofthe plate 10, and depending from the inneredges of these arms `12,andflanges 1 13 VthatY occup)T substantially vertical positions.

Formed integral with and 'projecting upwardly fromfthe outer portions ofthe-arms Al2, are flanges 14, the forward portions there-.f 1 ofextending forwardly with respect tothe rear edge of' theiplate :10, andformedv integral With the rear ends ofthe upturned flangesll and therearends of-thearms '12, are ears or plates y15 that are perforated .forythe rel ception of screws or`li'ke lfastening devices that are utilizedin attaching the cutter .to

a suitable support.

Formed inthe intermediate ortionsl of the arms`12 and the dependinganges 13, are short slots 16and occupyingl the lower porroject from theends of a small'roller 18, Iand which latter occupies-va positionimmediately to the reary and `parallel Kwith plate flO'.

Arranged beneath the plate 10 and the forward portions of combined papertensioning and deflecting membersV 19, and the forward end-s, ofthese'members are rigidly secured'to theforward portion of plate l0, inany suit-l able manner, either by being spot welded, or

by means of rivets or lilerfastening devices.

The rea-rl portions 20.0.f these combined tensioning and deflectingmembers 19 are curved so that they lit directly over the upperportionofthe roller 1:8, and t e intermediate portions of said members, orthose portions' directly in front of the-roller are bent so'as` to formdepending curved portions 2'1. i

These tensioning` members are preferably forme d of resi-lientmetaland'they are mounted sok that their curved rear-ends20fbear'with acertain degree ofv friction, upon that portion of theweb of paper p-that.passcs'over theroller 18.

When my improved paper cutter is positioned for use, it is ixed to asuitable support, preferably above or above and in front of a roll ofpaper and the web of the paper passes from the roll upwardly orforwardly over the roller 18 and beneath the rear portions 2O of thetensioning members.

The pressure of the portions 20 of the resilient tensioning members onthat portion of the paper that passes over roller 18 lirmly holds thepaper on the roller and due to the provision of the dependingintermediate portions 20 of the tensioning device, the free end of theweb of paper projects downwardly in front of the roller 18 so that itoccupies a position beneath the rear portion of plate 10.

Then a portion of the roll of paper is to be unrolled and torn olf, thedepending end of the web of paper beneath the plate 10 is engagedbetween the thumb and lingers and drawn downwardly and outwardly, untilthe desired amount of paper has been unrolled, and the web of paper isnow drawn upwardly and laterally so as to bear against the front edge 11of the plate 10, and thus, that portion of the paper beyond or in frontof the cutter will be torn of by engagement with the front edge 11 ofsaid plate 10.

As the unwound portion of the paper is thus torn off, the free end ofthe web or that portion beneath plate 10, will swing downwardly, awayfrom the plate 10 to a position immediately in front of and below theroller 18, which action is brought about the depending intermediateportions 20 of the tensioning device, which depending portions functionas delectors, and thus the end of the web of paper occupies a positionwhere it may be conveniently grasped when another portion of paper is tobe unwound and torn olf.

A roll paper cutter of my improved construction may be convenientlycombined with the ordinary or standard forms of roll paper holders, orsaid cutters may be attached to any convenient support above or in frontof a roll of paper that is mounted for rotation in suitable supports orbearings.

Thus, it will be seen that I have provided a roll paper cutter that isrelatively simple in construction. inexpensive of Vmanufacture, andwhich is very effective in performing the functions for which it isintended.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved roll paper cutter maybe made and substituted for those herein shown and described withoutdeparting from the spirit of my invention` the scope of which is setforth in the appended claims.

I claim as my invention:

1. A roll paper cutter comprising a plate having a tearing edge, armsformed integral with and projecting rearwardly from the ends of saidplate vertically disposed slots formed in the intermediate portions ofsaid arms, a roller having its ends journaled in said slots and aplurality of resilient paper tensioning and deilecting members havingtheir forward portions secured to the underside of said plate andextending rearwardly over said roller. p

2. A roll paper cutter comprisinga plate having a tearing edge, armsformed integral with and projecting rearwardly from the ends of the saidplate which arms are substantially Z-shape in cross section with slotsformed in the intermediate portions of said arms, a roller having itsends journaled in said slots, a plurality of combined paper tensioningand deflecting members having their forward portions secured to theunderside of said plate and extending rearwardly over said roller, andthe intermediate portlons of which members are curved downwardly to formpaper deectors. l

In testimon whereof I aiiix my signature.

AMES W. MCCLINTOCK.
